Principle

The free carboxyl groups of peptides used for plate coating can be covalently linked via reaction with the water-soluble peptide coupling reagent l-ethyl-3-(3-(dimethylamino)-propy1)carbodiimide (EDC). These peptides can subsequently be linked to amino groups that are attached to the surface of microtiter plate wells. The end result is a population of peptides directly coating the surface of the microtiter plate via peptide bonds.
